I'm finally putting a BAC valve back on to my car, my question is this:
If I've removed all emissions/thermowax/etc and don't need to hook up coolant lines to the BAC do I need to plug or seal any of the coolant ports on it? Or can I just install it as it is?
Thanks,

Sam

 

the coolant barbs can be left empty (they don't even need to be capped), or you can actually remove them by taking off the two philips screws on the side.
